You think that if you can do it on the tramp, you can do it on the snow, or at least I thought so. This isn't the case, however it doesn't hurt. I learned linkon loops and back flips on the tramp, which were easy to bring to snow because they are basic. things like cork spins 5,7,9/d-spins took a lot more. I could do those on the tramp for ever, but it took me almost a whole season to build up the stones to throw it. Once you do, you realize its not that different. The one thing that is really good is that the tramp builds a crazy good air sence. This helps to spot the landing and know where you are at all times. It also helps if you mess up, you can save yourself rather than just flailing ans still landing on your head. So the vertict that i come to is that the tramp, although it doesn't ensure you learn the stuff on snow, will deff help and make you more comfortable overall.
